Among the American physicians whose names are brought with praise before the British public in the Review before us, are Drs. Dunglison, Geddings, and Smith, of Baltimore, and Jackson (senior and junior,) of Boston. Though Dr. Dunglison is an Englishman born, we claim his professional merits chiefly for America, who has fostered, developed and matured, by appreciating and rewarding them. We sympathize in the gratification he must feel, at the emphatic and pre-eminent tribute rendered him in the preface, where he is classed _with_, yet _above_, the distinguished physicians of Berlin, Hamburg, Geneva, Madrid, and St. Petersburg, to whom obligations are acknowledged for valuable assistance. In No. 2, is a very favorable review of Dr. Dunglison’s late work on the Elements of Hygiene. Like his prior and large work on Human Physiology, (of which, as well as of his Medical Dictionary, America is the birth place,) this valuable treatise is rather _technical_ than _popular_; being designed more for medical than for general readers. In the same article, is a detailed notice of the before mentioned essay of Dr. Combe, on Hygiene—or, to give its proper title, “The Principles of Physiology applied to the Preservation of Health, and to the Improvement of Physical and Mental Education.” This is the work of which the Reviewer says 10,000 copies have been circulated in the United States; but as it has been stereotyped by the Harpers, and made a number of their “Family Library,” besides publication in other forms, we question if 20,000 copies be not nearer the truth. The whole range of physical authorship, we have long believed, does not present an equal to this modest little book of Dr. Combe’s, for curious, interesting, and valuable truth: not to physicians alone, or to {786} scholars, or to gentlemen, or to school-mistresses, but to every class of mankind, from the President of a College to the laborer in “his clouted shoon.” The topics it particularly treats of, are the structure and functions of the _skin_—of the _muscular system_—the _lungs_—the _bones_—and the _nervous system_, with the _mental faculties_, supposed to be connected with it. Annexed to each of these subjects are rules, “by the observance of which, each of them may be kept in health, and may conduce to the general health of the body.” “And thus the reader is led to wholesome customs, by being taught the _reason_ of their being wholesome.”
